Definitions
- Toilets that are provided in vehicles, or used for camping purposes or are otherwise portable, are typically made primarily of plastic. Constructing such toilet units of plastic not only is relatively inexpensive and allows simple construction thereof, but also the use of plastic saves weight, which is important in any type of vehicle, or for portability in general. Therefore conventional portable and mobile toilet units include a plastic toilet bowl, a plastic body positioned exteriorly of the toilet bowl, and a plastic toilet seat.
- the toilet environment is extremely harsh and plastic components—plastic toilet bowls in particular—have a tendency to degrade more quickly than desired as a result of attack by chemicals and light. While it is thus highly desirable to provide toilet bowls having improved characteristics, so as to extend the life thereof, that desirable goal cannot be achieved by compromising the cost and low weight criteria that are very important for portable and mobile toilets. For example it is not possible—in a manner consistent with low weight and low cost—to replace the plastic toilet bowl with a toilet bowl material, like porcelain, that has outstanding resistance to degradation but relatively high cost and weight.
- a portable or mobile toilet unit which is able to achieve a significantly longer life for the toilet bowl, and increase the hygiene associated therewith, while at the same time only minimally increasing the weight and cost of the toilet unit.
- This is accomplished according to the present invention by providing a non-polymeric, substantially poreless, material that is substantially not degraded as a result of contact with excrement, light, and toilet bowl cleaning agents, disposed interiorly of the plastic toilet bowl and for contacting liquid and materials passing through the toilet bowl open top.
- the material has an outlet adjacent the bottom thereof for leading sewage away from the toilet bowl.
- the material may be provided as a layer or coating of, for example, porcelain or glazed ceramic (each about 0.3125 inches thick, for example); glass; or corrosion resistant sheet metal, or sheet metal with a corrosion resistant substantially poreless interior coating, (e.g. each about 0.05 inches thick).
- the material comprises a thin-walled (that is having the minimum thickness necessary for structural integrity considering the material utilized) insert liner which is disposed within and is at least partially supported by (typically almost completely supported by) the interior of the plastic toilet bowl.
- the plastic toilet bowl itself can be made thinner than in conventional toilet units since it primarily only provides a supporting function; and since the insert liner is at least partially supported by the plastic toilet bowl, it can be thinner than it otherwise would have to be to have the sufficient structural integrity if it served as the only toilet bowl structure.
- the insert liner may be attached by adhesive directly to the toilet bowl interior surface, or may be attached thereto by mounting foam.
- the toilet unit also preferably comprises a liquid flush mechanism which flushes liquid (such as water, or a deodorant liquid as commonly used in conventional vehicle toilets) into and through the insert liner.
- the insert liner outlet is typically sealed by a lip seal to other components.
- the plastic body may include an annular plastic cover adjacent the toilet seat and an upper rim of the insert liner may be received by the annular plastic cover.
- the annular plastic cover may mount a plurality of nozzles for introducing flushing liquid into the toilet bowl, directed against the insert liner, and the plastic toilet bowl may have a substantially radially extending portion which supports the annular plastic cover.
- the plastic body may be rotatably supported by a socket, which in turn is rotatable about a substantially vertical axis and is mounted below the toilet bowl and insert liner.
- a funnel-shaped conduit communicating with a connection which passes through a wall of the socket, to lead sewage away from the toilet bowl outlet, e.g. to a holding tank either integral with the toilet unit or—in the case of most vehicles—distinct from the toilet unit.
- the toilet unit according to the invention is particularly suitable for use with vacuum flush toilets, such as sold by Sealand Technology, Inc. of Big Prairie, Ohio, such as under the “VACU-FLUSH” trademark.
- a common foot pedal actuator may be provided for operating a valve to supply flushing liquid to the nozzles, and to substantially simultaneously open a spherical segment valve to allow sewage to pass out of the insert liner through the outlet.
- FIG. 1 is a side view, partly in elevation and partly in cross-section, of an exemplary portable or mobile toilet unit according to the present invention
- FIG. 2 is an end view, partly in cross-section and partly in elevation, and partly in outline, of the toilet unit of FIG. 1;
- FIG. 3 is a schematic top view showing the common pedal actuator for the liquid flush valve, and the spherical segment valve for opening or closing the toilet bowl outlet, in the toilet unit of FIGS. 1 and 2;
- FIG. 4 is a side primarily cross-sectional view of an alternative construction of the base for the portable toilet according to the present invention.
- FIG. 5 is a side view of the base of FIG. 4 with a minor modification thereof.
- the toilet unit according to the present invention in one exemplary form, is shown generally by reference numeral 1 in FIGS. 1 and 2.
- the basic generally conventional components include a plastic toilet bowl 11 having an interior surface, an open top, and an exterior surface, a plastic body 2 positioned exteriorly of the toilet bowl 11 exterior surface, a plastic toilet seat 3 for partially closing the open top of a plastic toilet bowl 11 , and a plastic cover 4 for covering the toilet seat 3 . While these components are conventional, the plastic toilet bowl 11 according to the present invention may be made thinner than in conventional constructions of portable or mobile toilet units.
- a non-polymeric, substantially poreless, material that is substantially not degraded as a result of contact with excrement, light, and toilet bowl cleaning agents, is disposed interiorly of the plastic toilet bowl 11 and for contacting liquid and materials passing through the toilet bowl 11 open top.
- the material may be in the form of a layer or coating on the plastic toilet bowl 11 interior surface if the plastic of the toilet bowl 11 and the non-polymeric material are compatible.
- the material comprises a thin-walled insert liner 12 which is disposed within and is at least partially supported by the interior surface of the plastic toilet bowl 11 (preferably all or the majority of the support for the insert liner 12 is provided by the plastic bowl 11 ).
- the insert liner 12 also defines the outlet 8 adjacent the bottom thereof for leading sewage away from the toilet bowl 5 (collectively the plastic toilet bowl 11 with the insert liner 12 ).
- a suitable valve 9 preferably a conventional spherical segment valve.
- a water level 10 is typically established within the bowl 5 . Establishing the water level 10 so that it is substantially permanently maintained in the toilet bowl 5 indicates the tightness of the seal provided by the valve 9 , and assists in providing an odor free environment.
- the non-polymeric material, forming a layer, coating, or the preferred insert liner 12 may comprise or consist essentially of porcelain, glazed ceramic, glass, corrosion resistant sheet metal, or sheet metal with a corrosion resistant substantially poreless interior coating (e.g. enamel).
- the insert 12 is thin-walled, meaning that it has only the thickness necessary to provide sufficient structural integrity so that it does not crack or become easily damaged, considering that it is at least partially (if not substantially wholly) supported by the plastic toilet bowl 11 .
- the thickness of the insert 12 will depend upon the particular material used therefor; for example if the insert liner 12 is of corrosion resistant sheet metal, such as aluminum or stainless steel, it will typically have a thinner wall than if of porcelain or glazed ceramic.
- a typical nominal thickness of a sheet metal liner 12 is about 0.05 inches, a typical nominal thickness of a vitreous china (or other porcelain or glazed ceramic) insert 12 is about 0.3125 inches, and a typical nominal thickness of the plastic toilet bowl 11 when the insert 12 is used is about 0.125 inches.
- the insert 12 may be adhesively secured directly to the interior surface of the plastic toilet bowl 11 , or it may be attached to the plastic toilet bowl 11 interior surface by mounting foam, such as the polyurethane mounting foam 18 illustrated in FIGS. 1 and 2.
- mounting foam such as the polyurethane mounting foam 18 illustrated in FIGS. 1 and 2.
- Polyurethane mounting foam 18 is preferred since when used the tolerances need not be as tight when manufacturing the toilet bowl 5 components 11 , 12 , and because the foam 18 provides improved breaking strength as well as noise dampening.
- the plastic toilet seat 11 is supported at the bottom end thereof by a flange 13 of a socket 6 .
- the flange 13 includes a seal 14 which comprises a cylindrical section 15 for receipt of a concentric cylindrical section 16 of the insert liner 12 , and a lip seal 17 is also provided at the interface between the cylindrical section 15 and the concentric section 16 at the top of the cylindrical section 15 .
- the socket 6 mounts the valve 9 for rotation about a substantially horizontal axis.
- the insert liner 12 is placed within the plastic toilet bowl 11 , and then preferably the polyurethane mounting foam 18 is injected into a space between the bodies 11 , 12 —as illustrated in FIGS. 1 and 2 —and allowed to cure. Where the tolerances are sufficient, the exterior surface of the insert liner 12 may be adhesively secured substantially directly to the interior surface of the plastic toilet bowl 11 .
- the plastic toilet bowl 11 includes a substantially radially extending upper edge 20 which provides a circumferential seat for an annular plastic cover 19 , i.e. supports the substantially annular plastic cover 19 .
- Cover 19 supplies vertical play for the plastic body 2 .
- a downward force is transmitted to the cover 19 , which prevents the compression force from being transmitted to the insert liner 12 because the force is instead exerted on the plastic toilet bowl 11 and the plastic body 2 primarily via the substantially radially extending upper edge 20 .
- the plastic cover 19 receives the upper edge 12 ′ of the insert liner therein.
- the toilet unit 1 has a liquid flush mechanism which flushes liquid into and through the insert liner 12 .
- a liquid flush mechanism which flushes liquid into and through the insert liner 12 .
- the flush mechanism is provided by: a plurality of nozzles 21 mounted adjacent the bottom interior of the plastic cover 19 , as seen in FIGS. 1 and 2, and for spraying liquid directly on to the insert liner 12 interior surface; and a conventional valve assembly 25 for selectively applying water, or other flushing liquid, from a flush liquid source (e.g. a toilet tank, or a separate tank, or the surrounding environment if on a boat) 31 (see FIG. 3 ).
- the nozzles 21 spray flush liquid on substantially all portions of the interior surface of the insert liner 12 below the plastic cover 19 and above the bottom section 16 thereof.
- the socket 6 preferably mounts bowl 5 and body 2 so that they are rotatable about a substantially vertical axis for ease of installation, to allow proper positioning of the components thereof in areas where space is at a premium, such as in conventional vehicles in which the toilet unit 1 might be used (such as RVs, boats, caravans, trailers, and the like). Also rotation of the components 5 , 2 with respect to the socket 6 may be maintained even after installation in situations where it is desirable—again because of space considerations—to rotate the bowl 5 forwardly during use, and then to the side when not in use.
- the relative rotation between the socket 6 and the bowl 5 can be prevented or retarded, however, by the utilization of a locking mechanism, shown schematically at 22 in FIGS. 1 and 2.
- the locking mechanism 22 may comprise any conventional mechanism, such as a spring-biased clamp, which provides a clamping action between the seal 14 and the flange 13 which precludes relative movement.
- the spring force, or like force, provided by the biasing clamp of the locking mechanism 22 may be sufficient to preclude rotational movement between the parts 5 , 6 , completely, or merely be great enough to prevent any leakage and to hold the components 5 , 6 into a relative position to which they have been moved, yet allow at least 90° of relative rotation between them.
- seals 23 may be mounted on the support surface 7 for the toilet unit 1 so as to allow rotation of the plastic body 2 with respect to the mounting surface 7 . It is then necessary to provide a recess—shown only schematically at 2 ′ in FIG. 2 —for the pedal 24 to accommodate the relative rotation between the part 2 and the support 7 while allowing the pedal 24 to be in a relatively fixed position with respect to the vertical axis rotation of the body 2 .
- the pedal actuator 24 preferably substantially simultaneously actuates both the conventional flush liquid valve 25 and the spherical segment valve 9 for closing the outlet 8 . That is upon pressing down on the pedal 24 , the valve 25 is caused to be open causing flushing liquid to pass from the source 31 through the nozzles 21 into contact with the interior surface of the insert liner 12 , while at the same time the valve segment 9 is rotated about a substantially horizontal axis to move to an open position allowing liquid and other materials within the toilet 5 to flow through the outlet 8 into a funnel-shaped outlet unit 26 mounted within the socket 6 .
- the funnel-shaped outlet 26 is connected via a connecting piece 27 to one or more connecting channels 28 , 28 ′.
- a number of different channels 28 , 28 ′, which pass through the wall of the socket 6 may be provided to facilitate easy mounting of the unit 1 in cramped locations, such as on vehicles. Any connecting channel 28 , 28 ′ not used is plugged.
- the connecting channel 28 is illustrated in FIG. 1 connected up to a conventional vacuum source 29 , and a conventional holding tank 30 , such as used in the vacuum toilets sold by Sealand Technology Inc. of Big Prairie, Ohio, including under the “VACU-FLUSH” trademark, and/or such as illustrated in U.S. Pat. Nos. 3,663,970, 4,672,690, 5,408,704, 5,621,924, and/or 5,681,148.
- the vacuum source 29 and the holding tank 30 are mounted where convenient in the vehicle in which the toilet unit 1 is positioned.
- the actuator pedal 24 also automatically connects the interior of the toilet bowl 5 to a vacuum tank or the like.
- the base of the toilet unit is revised, providing a simplified pedestal arrangement.
- components functionally comparable to those in FIGS. 1-3 are shown by the same reference numeral plus 100 .
- FIG. 4 one version of part of the plastic toilet bowl 111 is shown on the left, but omitted on the right for clarity of illustration, and in FIG. 5 the elements 11 , 12 have been removed completely.
- the upper portion of the toilet unit 101 is preferably substantially the same as that of the toilet unit 1 .
- Other versions of the element 111 may also be provided, such as having a flange that is held in place by the bolts 34 with nuts 35 .
- FIGS. 4 and 5 embodiment the clamps 22 of FIGS. 1 and 2 have been replaced by the conventional plurality (e.g. four) of fasteners 34 , 35 , which compress the elastomeric seal 36 between the flanges 33 , 113 .
- the seal 36 also cooperates with the valve 109 , which is mounted for pivotal movement about a substantially horizontal axis by the pivot pins 37 .
- the funnel shaped interior 126 of the socket 106 ends in an outlet opening 38 that extends completely into the larger diameter conduit 39 .
- the discharge opening 40 of the conduit 39 is larger in cross-sectional area (e.g. has a larger diameter) than opening 38 .
- the pedal actuator 124 is simpler than the actuator 24 .
- FIG. 5 embodiment differs from that of FIG. 4 only in the position of the discharge outlet 40 , the rear position of FIG. 5 being preferred to that of FIG. 4 .
- the material which provides enhanced longevity and hygiene that is disposed in association with the interior surface of the plastic toilet bowl 11 may be provided by a metal coating (e.g. galvanized) on plastic material, or by producing a compound material such as by casting plastic around a porcelain insert, or pressing an insert into a prefabricated carrier body.
- a metal coating e.g. galvanized
- the insert 12 may simply be slipped into the toilet bowl 11 without a connection between them, or by providing spaced pressure and tension release components.
